sp., Modiola solenoides, Gervillia aviculoides, and very abundant 
Rhynchonella Orbignyt. 
Beds of lithographic limestone (f) form a horizon easy of recogni- 
tion, and are best developed in Gebel Hamaiyir. They have furnished 
some sections of Belemnites and a cast of Quenstedticeras. At the 
same level have been found a fragment of Pachyceras, large 
Terebratule, related to T. Lamberti and T. suprajurensis, as also 
Zeilleria Parandiert. These beds were regarded as representing the 
Upper Callovian and Oxfordian, perhaps even the Upper Jurassic. 
(g) This latter horizon seemed to be indicated by a fragment of a 
Lytoceras, having the characters of L. Lnebigi var. strambergensis. 
The Jurassic strata are thus developed on a large scale in this 
portion of Egypt, as are also the Lower Cretaceous beds, which 
overlie them in great thickness. 
(h) The Lower Cretaceous strata were noted as represented by 
limestone containing grains of quartz or small ferruginous oolites. 
These were stated to have yielded Knemiceras syriacum, Protocardia 
hillana, Eovradiolites Rousseli, Neithea quinquecostata; a lower 
stratum seemed particularly rich in species of large Trigonias, 
Tr. like crenulata and Tr. like sinuata. These beds were regarded 
as the extension of the well-known Lower Cretaceous formations of 
the Lebanon, where they represent the “ Vraconnian”’. Like the 
Jurassic, these had never yet been recorded, either in South Palestine 
or in Egypt. It is of interest to note, however, that M. C. Barthoux 
has also noted the Knemiceras beds at the foot of Gebel Shabrawet, 
one of the hills near Faied Station (Ismailia-Suez line) to the west of 
the Suez Canal. 
(2) The highest beds of the series studied are yellowish, very 
' fossiliferous limestones of typically Cenomanian age, with such 
characteristic fossils as Neolobites Vibrayei, Exogyra flabellata, 
and Orbitolina concava, race minor. 
The larger work, “ Les Terrains Secondaires dans le Massif du 
Moghara a lest de V’isthme de Suez d’aprés les explorations de 
M. Couyat-Barthoux et M. H. Douvillé,” deals with the paleontology 
of the area in greater detail, full descriptions being given of the 
principal Cephalopoda, Gasteropoda, Lamellibranchiata, Brachiopoda, 
and Foraminifera in the various formations. 
The results differ in no important respect from those recorded in 
the first paper; the Knemiceras is, however, K. Uhligi Chofiat, 
and not the closely related K. syrvacum. 
The war brought further study of North Sinai to a conclusion for 
some years, and only in the season of 1918-19 did M. Fourtau 
(acting in his capacity of paleontologist to the Geological Survey of 
Egypt) commence a detailed examination of this portion of Northern 
Sinai, extending his researches eastward to embrace the massif of 
Gebel Helal in 1919-20. In the latter period Messrs. Moon and 
Sadek examined an area of some 8,000 square kilometres in North-
